Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the description of the present disclosure, it should be understood that the terms "center", "upper", "lower", "top", "bottom", "inner", "outer", and the like indicate an orientation or positional relationship based on the orientation or positional relationship that a user is in when using the rotation module.

The embodiment of the present disclosure provides a rotation module, including:

two rotating arms 200;

a bracket 100 having a track groove 110, said bracket 100 being located between two of said swivel arms 200; wherein the rotating arm 200 can rotate around the bracket 100 at the rotating center of the rotating arm 200;

each of the rotary arms 200 includes:

a first rotating member 210, a first end 211 being located in the track groove 110;

a second rotating member 220 rotatably connected to the second ends 212 of the bracket 100 and the first rotating member 210, respectively; wherein the second end 212 is opposite the first end 211;

when the rotating module is in a folded state, the rotating center of the first rotating member 210 is a first position of the groove wall of the track groove 110;

when the rotating module is in the unfolded state, the rotation center of the first rotating member 210 is a second position of the groove wall of the track groove 110, and the second position is located between the center position of the track groove 110 and the first position;

the rotation center of the first rotating member 210 is a rotation center of the rotating arm 200.

As shown in fig. 1 to 3, the second rotating member 220 of each rotating arm 200 can rotate with both the bracket 100 and the second end 212 of the first rotating member 210, and the first end 211 of the first rotating member 210 can rotate at different positions on the groove wall of the track groove 110 of the bracket 100, namely: the rotation center of each rotation arm 200 at least includes the rotation center between the second rotation member 220 and the bracket 100, the rotation center between the first rotation member 210 and the second rotation member 220, and the rotation center between the first rotation member 210 and the bracket 100. The second rotating member 220 rotates relative to the bracket 100, and simultaneously, the first rotating member 210 rotates relative to the second rotating member 220, and the first rotating member 210 rotates in the track groove 110.

The rotating center between the second rotating piece and the bracket is relatively fixed, the rotating center between the first rotating piece and the second rotating piece is also relatively fixed, but the rotating center between the first rotating piece and the bracket is changed within a preset range. The preset range may be any range between the center position of the track groove to the edge position of the track groove for a single rotating arm. When the foldable bicycle is in the unfolded state and the folded state, the rotating centers between the first rotating member and the bracket are respectively two limit positions of a preset range. The center of rotation of the first end 211 of the first rotating member is between the first position and the second position between the unfolded state and the folded state.

In some embodiments, the first end 211 of the first rotating member 210 has an arc-shaped outer surface, and the arc-shaped outer surface contacts with a groove wall of the track groove 110. As shown in fig. 1, the groove wall of the track groove 110 is matched with the arc-shaped outer surface, that is, the cross-sectional shape of the track groove 110 is substantially the same as the cross-sectional shape of the first end 211 of the first rotating member 210, so as to ensure that the first end 211 of the first rotating member 210 can smoothly rotate in the track groove 110.

As shown in fig. 3, the rotating arm 200 can support the folding screen in the unfolded state, and can leave a certain space for the folded folding screen in the folded state, thereby reducing the squeezing of the folding screen. In practical applications, as shown in fig. 2, the unfolded state refers to: the two rotating arms 200 are approximately 180 degrees, when the folding screen 300 of the electronic equipment is applied to the electronic equipment, the folding screen is exposed, and at the moment, a user can obtain large-screen display. As shown in fig. 3, the folded state means: the two rotating arms 200 are approximately 0 degree, and when the folding screen 300 of the electronic device is applied to the electronic device, the folding screen is hidden. Both the rotating arms 200 can be rotated relative to the supporting frame 100 by the second rotating member 220 to achieve the folded state or the unfolded state.

As shown in fig. 3, the first rotating member 210 may directly apply a force to the folding screen 300, relative to the second rotating member 220. The deformation of the folding screen 300 is greater in the folding area (also referred to as the portion of the folding screen 300 aligned with the support 100). In the process of rotating from the unfolding state to the folding state, the rotating center of the first end 211 of the first rotating member 210 can gradually move towards the edge of the track groove 110, in the process, the first rotating member 210 can avoid the folding screen 300, so that the acting force of the second rotating member 220 on the folding screen 300 is reduced, even, the second rotating member 220 has no acting force on the folding area of the folding screen 300, the stress of external force on the folding area of the folding screen 300 is reduced, and the protection effect on the folding screen 300 is improved.

Therefore, in the embodiment of the present disclosure, by the cooperation of the first rotating member 210, the second rotating member 220 and the bracket 100, in the unfolded state, the first end 211 of the first rotating member 210 is closer to the center position of the track slot relative to the rotation center of the bracket 100, and in the folded state, the first end 211 of the first rotating member 210 is farther from the center position of the track slot relative to the rotation center of the bracket 100, that is, the first end 211 of the first rotating member 210 is closer to the edge of the track slot relative to the rotation center of the bracket 100. At this time, the first end 211 of the first rotating member 210 is farther away from the maximum deformation position of the folding screen 300 relative to the unfolded state, so that the damage to the folding screen 300 is reduced. The rotation of the first rotating member 210 and the track groove 110 in the center of the rotation is changed, so that the first rotating member 210 can better adapt to the natural bending of the folding screen 300, and the protection effect on the folding screen 300 is improved.

In some embodiments, the degree of freedom of the rotation pair formed by the first rotating member 210 and the track groove 110 of the bracket 100 is greater than the degree of freedom of the rotation pair formed by the first rotating member 210 and the second rotating member 220; similarly, the degree of freedom of the revolute pair formed by the first rotating member 210 and the track groove 110 of the bracket 100 is greater than the degree of freedom of the revolute pair formed by the second rotating member 220 and the bracket 100. For example: the second rotating member 220 is surface-engaged with the bracket 100, the second rotating member 220 is surface-engaged with the second end 212 of the first rotating member 210, and the first end 211 of the first rotating member 210 is point-engaged or line-engaged with the track groove 110. At this time, a similar linkage mechanism is formed among the bracket 100, the second rotating member 220, and the first rotating member 210.

Without limitation, the first end 211 of the first rotating member 210 may have a substantially arc shape when viewed from different time points when the unfolded state and the folded state are changed.

Without limitation, the groove walls of the tracking groove 110 are arc-shaped. The arc may be circular or non-circular. For example: the groove wall of the track groove is in a non-circular arc shape, such as: the groove wall of the track groove is in a roughly elliptic arc shape, a parabola shape or the like.

In other alternative embodiments, the track groove 110 has: a first mounting hole 120;

the second rotating member 220 has: a shaft hole 221 aligned with the first mounting hole 120;

the rotation module further includes: the shaft core 290, the shaft core 290 penetrates the first mounting hole 120 and the shaft hole 221.

As shown in fig. 1, the second rotating member 220 can rotate relative to the frame 100 by the engagement of the shaft core 290 with the shaft sleeve.

In practical applications, the shaft core may form an integral structure with the wall of the first mounting hole or with the wall of the shaft hole by molding or machining.

In other alternative embodiments, the second rotating member 220 further has: the groove 222 is characterized in that the groove wall of the groove 222 is arc-shaped;

the second end 212 of the first rotating member 210 is located in the groove 222.

In the embodiment of the present disclosure, while the second rotating member 220 rotates relative to the bracket 100, the second end 212 of the first rotating member 210 is driven to move along the groove wall of the groove 222, and since the groove wall of the groove 222 is arc-shaped, the moving track of the first rotating member 210 in the groove 222 is arc-shaped, that is, the first rotating member 210 rotates relative to the second rotating member 220.

In some embodiments, a portion of the outer surface of the second end 212 of the first rotating member 210 facing the groove 222 is rounded. The first rotating member 210 with the circular arc-shaped outer surface is matched with the groove wall of the groove 222, so that the second end 212 of the first rotating member 210 can rotate in the groove 222 more smoothly.

As shown in fig. 1, the walls of the groove 222 are semi-circular,

in other alternative embodiments, the first rotating member 210 further includes:

a first tooth portion 213 located at a region of the first rotating member 210 other than the first end 211 and the second end 212;

the swivel arm 200 further includes:

and a first gear structure 230 engaged with the first tooth portion 213.

In the embodiment of the present disclosure, each of the first tooth portion 213 and the first gear structure 230 includes at least two teeth, and the first tooth portion 213 and the first gear structure 230 are engaged.

The first rotating piece is located between the support and the first gear structure, and the first rotating piece and the support rotate relatively and simultaneously drive the first gear structure to rotate through the meshing of the first tooth portion and the first gear structure. When the number of the first gear structures is at least two, the two first gear structures are in meshing connection, at the moment, the rotation center is also formed between the two first gear structures, and the rotation center of the rotating arm is increased due to the matching of the first gear structures and the first rotating member. The multiple rotation centers of each rotation arm further restrain stress concentration in the folding process, and damage to the folding screen is reduced.

During fold condition, the rotor arm can further make two rotor arms keep away from folding screen through rotating in first gear structure position department, and when reducing fold condition, two rotor arms are to the extrusion of folding screen. As shown in fig. 3, at the position of the first gear structure 230, there is a space 400 between the two rotating arms 200 and the folding screen 300.

Without limitation, as shown in fig. 3, the rotation module according to the embodiment of the disclosure can implement a drop-shaped folding of the folding screen 300, and reduce gaps in other areas outside the folding area of the folding screen 300.

The number of the first gear structures 230 of each rotating arm 200 may be one or at least two. As shown in fig. 1, when each of the rotating arms 200 includes at least two first gear structures 230, the structures of each of the first gear structures 230 may be the same or different, two adjacent first gear structures 230 are engaged, and one first gear structure 230 is engaged with the first tooth portion 213. For example: as shown in fig. 1, each of the rotary arms 200 includes two first gear structures 230, wherein one of the first gear structures 230 is a cylindrical gear, and the other first gear structure 230 is a rod-shaped gear, and the cylindrical first gear structure 230 is located between the first tooth 213 and the rod-shaped first gear structure 230; the columnar first gear structure 230 meshes with the first tooth portion 213, and also meshes with the rod-shaped first gear structure 230.

In other alternative embodiments, the first rotating member 210 further includes: a pin 214;

the rotation module further includes:

and a connecting member 240 having at least two connecting holes 241, at least two connecting holes 241 respectively receiving the pin 214 and the gear shaft 231 of the first gear structure 230 to restrict the first gear structure 230 and the first tooth 213 from being separated.

As shown in fig. 1, the pin 214 and the gear shaft 231 of the first gear structure 230 are respectively inserted into the connecting holes 241 at different positions, and the connecting member 240 strengthens the connection between the first gear structure 230 and the first rotating member 210, thereby ensuring the reliability of the meshing between the first tooth portion 213 and the first gear structure 230.

Without limitation, the connector is a sheet.

In other alternative embodiments, the swivel arm 200 further comprises:

a support bracket 250 coupled to the first gear structure 230 and having a mounting location 2511; the mounting location 2511 is used for connecting a housing of an electronic device.

As shown in fig. 3, the supporting frame 250 may directly contact with the foldable screen, and has a supporting function on the foldable screen. Alternatively, the support frame 250 is in contact with the folding screen through the housing of the electronic device.

Without limitation, the mounting location 2511 includes: mounting holes or mounting grooves.

In other alternative embodiments, the swivel arm 200 further comprises:

a link 260 having a first portion 261 and a second portion 262 connected to the first portion 261; the first portion 261 includes a second tooth 2611, and the second portion 262 is connected with the supporting bracket 250;

a second gear structure 270, a gear shaft of the second gear structure 270 being connected to the bracket 100, the second gear structure 270 being engaged with the second tooth portion 2611;

Folding or unfolding of the two rotary arms 200 may also be achieved by the geared rotation of the second gear structures 270 of the two rotary arms 200. In practical applications, the meshing rotation of two adjacent second gear structures 270 may be synchronized with the rotation of the second rotating member 220 relative to the bracket 100. Since the second gear structure 270 is connected to the bracket 100, the cooperation of the first rotating member 210 with the supporting frame 250, the connecting rod 260 and the second gear structure 270 further reinforces the cooperation of the first rotating member 210 and the bracket 100, so that the first rotating member 210 can stably rotate in the track groove 110 without easily disengaging from the track groove 110.

The second rotating member 220 has a shaft hole 221 at one end and a circular slide rail (i.e., a groove 222) at the other end. The second end 212 of the first rotating member 210 has a circular sliding slot 2522, and the first end 211 has a first tooth 213 and is connected to a pin 214. The first rotating member 210 is respectively engaged with the bracket 100 and the second rotating member 220, and the first rotating member 210 can rotate with respect to the bracket 100 within a certain angle.
